Steve Hays addresses the Arminian claim that it's possible for Christians to lose their salvation.

J.C. Thibodaux, one who believes Christians can lose their salvation, responds: "Just as Israel fell in the wilderness after being saved from the wrath of Pharaoh, so the scriptures warn us against likewise incurring God's judgment after He has shown us His goodness." Of course, this completely ignores the fact that while the people of Israel did "fall away" and were disciplined, they were still God's chosen people and the covenant made with Abraham remained intact. Paul makes this pretty clear in Romans 11:1.
